After machining, brass parts are often annealed (softened) for subsequent bending, swaging or crimping. A partial anneal
down to 60±10 RB is recommended for 90° bends, a full anneal down to 35±15 RB is recommended for pins or terminals
that are swaged (riveted) to a circuit board or crimped to a wire.
†RoHS-2 directive 2011/65/EU, exemption 6c allows up to 4% lead as an alloy agent in copper.
*International Annealed Copper Standard, i.e. as a % of pure copper.
INSULATOR INFORMATION:
NYLON 46
(Stanyl TE250F6 {30% glass} or TE250F9 {45% glass}, black)

Compliance Statement for DRC Conflict Free products.
Reference:
Dodd-Frank Wall Street Reform and Consumer Protection Act, Section 1502, reporting requirements for users of conflict
minerals.
“Conflict minerals,” are Columbite-tantalite (coltan), cassiterite, gold, wolframite, or their derivatives; or any other mineral
or its derivatives determined by the Secretary of State to be financing conflict in the Democratic Republic of the Congo
(DRC) or an adjoining country. Metals derived from these minerals are tin, tantalum, tungsten, and gold. By this definition,
the only minerals of concern that may be found in Mill-Max products are tin and gold.
Mill-Max Mfg.Corp. hereby certifies that its products are manufactured with tin and gold that is derived from material that
is considered DRC Conflict Free. Mill-Max provides this assurance as a result of a due diligence process that includes
traceability to the source and in some cases the identification of recycled and scrap materials included in the subject
material.
